1 vers. 20100604 national spatial data infrastructure training program Value of Metadata Introduction to Metadata An overview of the value of metadata to geospatial data distribution, data management and project management.

2 national spatial data infrastructure training program Intro to Metadata: Value of Metadata 2 Learning Objectives After completing this module the student can: explain the geospatial data distribution role of metadata explain the geospatial data management role of metadata explain the geospatial project role of metadata make the business case for metadata implementation

3 national spatial data infrastructure training program Intro to Metadata: Value of Metadata 3 Utility of Metadata Metadata can support: data distribution data management project management If it is: considered a component of the data created during data development populated with rich content derive classify collect planimetricimagery analysis alternative committee review PLAN charette meta

4 national spatial data infrastructure training program Intro to Metadata: Value of Metadata 4 Data Distribution via Metadata metadata publication data portals data discovery

5 national spatial data infrastructure training program Intro to Metadata: Value of Metadata 5 Distribution: Data Discovery The descriptive content of the metadata file can be used to identify, assess and access available data resources. online access order process contacts use constraints access constraints data quality availability/pricing keywords geographic location time period attributes

6 national spatial data infrastructure training program Intro to Metadata: Value of Metadata 6 Distribution: Metadata Publication A metadata collection can be published to the Internet via: web accessible folder (waf) website catalog Z39.50 metadata clearinghouse metadata service geospatial data portal Internet Metadata Collection User Query Internet / Intranet Data Set

10 national spatial data infrastructure training program Intro to Metadata: Value of Metadata 10 Data Management via Metadata Data Accountability Discovery & Re-use Maintenance & Update Data Liability

11 national spatial data infrastructure training program Intro to Metadata: Value of Metadata 11 Management: Maintenance and Update Data Maintenance: Are the data current?  older than ten years?  prior to the hurricane? Are the data valid?  prior to most current source data  prior to most current methodologies Data Update: Contact information Distribution policies, availability, pricing, URLs New derivations of the data set

12 national spatial data infrastructure training program Intro to Metadata: Value of Metadata 12 Management: Data Discovery & Reuse Metadata marketing in the past… If you create metadata, other people can discover your data New and improved message… If you create metadata, you can find your own data

13 national spatial data infrastructure training program Intro to Metadata: Value of Metadata 13 Find you data by: themes / attributes geographic location temporal character analytical methods used sources and contributors data quality Discoverable data is usable data Monument to the Discoverers in Lisbon, Portugal Management: Data Discovery & Reuse

14 national spatial data infrastructure training program Intro to Metadata: Value of Metadata 14 Management: Data Accountability Metadata is an exercise in data accountability. It requires you to assess: What do you know about the data set? What don’t you know about the data set? What should you know about the data set? Are you willing to associate yourself with the metadata record ?

15 national spatial data infrastructure training program Intro to Metadata: Value of Metadata 15 Management: Data Accountability Repeatable process: methods variables analytical parameters Defensible process: public participation decision-making increasingly GIS-savvy public requires consumer information INPUT RESULTS

16 national spatial data infrastructure training program Intro to Metadata: Value of Metadata 16 Management: Data Accountability Return on Investment Catalog assessment: # times data occurs, in-house, as source # times data occurs, external, as source significance of source contribution methods To facilitate assessment use standardized tilting schemes indicate preferred data set citation w/in Use Constraint Statement

17 national spatial data infrastructure training program Intro to Metadata: Value of Metadata 17 Management: Data Liability Metadata is a declaration of: Purpose the originator’s intended application of the data Use Constraints inappropriate applications of the data Completeness features or geographies excluded from the data Distribution Liability explicit liability of the data producer and assumed liability of the consumer What to do… What not to do…

18 national spatial data infrastructure training program Intro to Metadata: Value of Metadata 18 Project Management via Metadata Project Monitoring Project Coordination Project Planning Contract Deliverables

19 national spatial data infrastructure training program Intro to Metadata: Value of Metadata 19 Project Management: Project Planning Project design document descriptions & intent geographic and temporal extent source data attributes requirements Benefits: expectation are clearly outlined metadata is integrated into the process provide medium to record progress

20 national spatial data infrastructure training program Intro to Metadata: Value of Metadata 20 Project Management: Project Monitoring Monitor data development status QA/QC assessments needed changes Requires that the metadata be actively maintained and reviewed time milestones

21 national spatial data infrastructure training program Intro to Metadata: Value of Metadata 21 Project Management: Project Coordination Common reference for: descriptions & parameters keywords, vocabularies, thesauri contact information attributes distribution information If reviewed regularly by all participants, improved opportunity for coordinating: source data analytical methods new information template

22 national spatial data infrastructure training program Intro to Metadata: Value of Metadata 22 Project Management: Contract Deliverables As a key component of the data, metadata should be part of any data deliverable For best quality metadata, provide: classification and/or validation schema metadata content template metadata specification manual Provide a sample metadata record if possible

23 national spatial data infrastructure training program Intro to Metadata: Value of Metadata 23 Conclusions Metadata is simply information about data Information that you need to effectively: locate manage utilize internal and external data resources. Creation of robust metadata is in your OWN best interest!

24 national spatial data infrastructure training program Intro to Metadata: Value of Metadata 24 Summary This is the conclusion of: Value of Metadata. You should be able to: explain the geospatial data distribution role of metadata explain the geospatial data management role of metadata explain the geospatial project role of metadata make the business case for metadata implementation
